Fiberglass reinforced plastic and glass-lined steel

FRP is an organic composite material, while glass is an inorganic material; both are excellent materials for coatings or linings.

Fiberglass: Its scientific name is glass fiber reinforced plastic; it is also known as FRP (Fiber Reinforced Plastics), that is, fiber-reinforced composite plastic. Depending on the type of fiber used, they are classified into glass fiber reinforced composite plastics (GFRP), carbon fiber reinforced composite plastics (CFRP), boron fiber reinforced composite plastics, and so on. It is a composite material that uses glass fibers and their products (such as glass cloth, tape, felt, yarn, etc.) as reinforcing materials, with synthetic resin as the matrix material. Fiber-reinforced composite materials are composed of reinforcing fibers and a matrix. Fibers (or whiskers) have a very small diameter, generally below 10 μm; they have few and small defects, with a fracture strain of around 30 parts per thousand or less. They are brittle materials that are prone to damage, fracture, and corrosion. Compared to fibers, the matrix has much lower strength and modulus, but it can withstand large strains; it often exhibits viscoelasticity and elastoplasticity, making it a ductile material. Enameled steel: It is made by applying a ceramic glaze with a high silicon content to the surface of metal, and then firing it at 950°C to ensure that the glaze adheres tightly to the surface of the metal substrate. Therefore, it boasts the dual advantages of glass-like chemical stability and metal strength. Differences in the properties of porcelain enamel and glass-lined steel: Porcelain enamel: A metal surface is coated with multiple layers of ceramic glaze, which are then fired in a furnace at around 800°C; as a result of physical and chemical reactions, a composite material is formed in which the glaze bonds with the metal. Metals for enamel include: copper, aluminum, low-carbon steel... etc. Primarily used for decoration and in jewelry, as well as for surface decoration and corrosion protection of building materials; also used in everyday products such as bathtubs, water heaters, and water tanks ； Therefore, although enamel is classified into artistic enamel, household enamel, sanitary enamel, architectural enamel, cast-iron enamel, etc., it is generally referred to as household enamel. Glass lining: A glassy glaze with special properties, which is formed on a metal substrate by heating it in a furnace at around 820–950°C. A metal matrix refers to carbon steel, stainless steel containers, pipes, and other materials of certain strength used in various petrochemical equipment ； Primarily used as anti-corrosion equipment for chemical processes involving high and low temperatures, pressure, and corrosive environments, for reaction and storage purposes; these devices are collectively referred to as glass-lined equipment! Enameled steel was known as industrial enamel before the late 1960s.
